But each time the fireEvent is fired, I get this error message into Chrome's console :Uncaught TypeError: Object [object Object] has no method 'apply'Ext.define.doFireExt.define.fireExt.define.doDispatchEventExt.define.dispatchEventExt.define.doFireEventExt.define.fireEvent(anonymous function)call

However, the task is repeating and is cancelling like I expected.
Am I doing something wrong or is it a bug ?
